Chapter 7 Flashcards
flexibility
ability to move a joint through its complete range of motion or The normal extensibility of all soft tissues that allow the full range of motion of a joint
extensibility
capability to be elongated or stretched
dynamic range of motion
the combination of flexibility and the nervous sytem’s ability to control this range of motion efficiently
neuromuscular efficiency
the ability of the neuromuscular system to allow agonists, antagonists and stabilizers to work synergistically to produce, reduce, and dynamically stabilize the entire kinetic chain in all three planes of motion
how well the nervous and muscular systems work together to
create movement
postural distortion patterns
predictable patterns of muscle imbalances
relative flexiblity
the tendency of the body to seek the path of least resistance during functional movement patterns
muscle imbalance
alteration of muscle length surrounding a joint
reciprocal inhibition
the simultaneous contraction of one muscle and the relaxation of its antagonist to allow movement to take place
altered reciprocal inhibition
the concept of muscle inhibition caused by a tight agonist which inhibits its functional antagonist
synergistic dominance
the neuromuscular phenomenon that occurs when inappropriate muscles take over the function of a weak or inhibited prime mover
Arthrokinematics
the motions of joints in the body
arthrokinetic dysfunction
altered forces at the joint that result in abnormal muscular activity and impaired neuromuscular communication at the joint
autogenic inhibition
the process by which neural impulses are greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles
pattern overload
consistently repeating the same pattern of motion which may place abnormal stresses on the body
Davis’s law
states that soft tissue models along the line of stress
